Overview Models write backend code that passes the happy-path test and falls over on everything else: the race condition under load, the N+1 that melts the database, the API contract that breaks every client the day you change it. Someone has to reason about the system, not just the snippet, and that someone is you. As a Backend Engineer you'll stress-test how models design services, data models, and APIs, expose where their reasoning breaks under real load, and write the answers a strong backend engineer would stand behind. What you’ll actually do Probe backend reasoning across service design, data modeling, and API contracts, and see where the model's design falls apart. Find the failures that matter : race conditions, N+1 queries, bad indexes, and breaking changes hiding in a clean-looking diff. Write the correct design when the model falls short, with the scaling and consistency trade-offs made explicit. Roles this fits Common backgrounds:...

Overview The newest models can spin up a full analysis in minutes - load the data, pick a method, produce charts and a confident conclusion. Someone has to check whether the statistics actually hold up, and that someone is you. As a Data Scientist you’ll evaluate AI-generated analyses on real datasets, stress-test the reasoning behind them, and write the judgments that teach the next generation of models what rigorous data work looks like. What you’ll actually do Evaluate AI-built analyses on real datasets: the method choice, the assumptions, and whether the conclusion actually follows from the numbers. Red-team the statistics to expose leakage, p-hacking, confounded comparisons, and confident nonsense before real users trust them. Write the better analysis when the model falls short: sound methodology, honest uncertainty, clear takeaways. Roles this fits Common backgrounds: Data Scientist, Data Analyst, Analytics Engineer. What we look for...
